Clamp a hose adapter to the end of the 1/2" polyethylene tubing. Attach a pressure reducer to the hose adapter at the end of the tubing by screwing the two ends together (Image 1). To help prevent leaks, apply Teflon tape to the threads of the reducer. Slide a small clamp onto the 1/2" tubing. Insert the tubing into the other end of the reducer. Slide the clamp up to the reducer and crimp (Image 2).
Mark the location for the first nozzle on the 1/2" tubing. Poke a hole through the pipe using a landscaping staple (Image 1). Push the microsprayer nub into the hole and listen for a snap (Image 2). This indicates that there is a good connection. Finish installing the other microsprayer nozzles about five to six feet apart for ideal coverage. Secure the tubing to the ground with landscaping staples.
Prior to running the system, remove the nozzles and allow the water to flush any debris out of the pipe. Reinsert the nozzles and place at least six inches above the soil surface.
Cover the 1/2" polyethylene tubing with mulch or topsoil so that the nozzles are the only visible indicator of the microsprayer system.
